# ECU Connect vs DynoRoad

The clearest difference is rating: DynoRoad at 5.0 against ECU Connect's 4.0. DynoRoad also leads on update cadence (weekly vs every 3 weeks). ECU Connect's advantage is ratings volume (88 vs 1) and review sentiment (62% vs 38%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

DynoRoad holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: ECU Connect has 88 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 62% of ECU Connect's written reviews are positive against 38% of DynoRoad's, so the app with the better star average is not the one people write more warmly about.

ECU Connect ships an update every 3 weeks, DynoRoad weekly. The most recent releases landed on October 5, 2026 and September 23, 2026 respectively.
